To work the SPPF patcher you need to have a) the default variant of your map (unmodded) and b) the modded/edited version of your map.
Just run the SPPF patcher as an admin and put the maps in the correct path areas and hit create SPPF patch.
Then all people need to do to apply the patch is for them to apply the patch file to the default (unmodded) map with the patcher.
